Descriptions

The collator implementation in i18n/ucol.cpp in International Components for Unicode (ICU) 52 through SVN revision 293126, as used in Google Chrome before 40.0.2214.91, does not initialize memory for a data structure, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted character sequence.

La implementación collator en i18n/ucol.cpp en International Components for Unicode (ICU) 52 hasta la revisión SVN 293126, utilizada en Google Chrome anterior a 40.0.2214.91, no inicializa la memoria para una estructura de datos, lo que permite a atacantes remotos causar una denegación de servicio o posiblemente tener otro impacto no especificado a través de una secuencia de caracteres manipulada.
